    Rated 5 out of 5 by Good Product Great for engine start, slow and fast charge. Needs to be plugged in so you'll probably need an extension lead if you want to start a car or charge it in situ. 05 June 2016
    Rated 5 out of 5 by Nice bit of kit A strong and sturdy charger with the feel of something that will last. As always, the cables could do with being a bit longer but a nice, simple to use charger that seems to do the job very well. It's the sort of kit that you want to leave on the floor when charging, but the cables only just reach into the bonnet of a 320 BMW (which is quite a low ride) Not a 'deal-breaker', but another foot of cable would make it even better. Not used the start function yet but it certainly performs well as a charger, easily outperforming the big old tin box that it has replaced. 17 March 2016

    Rated 4 out of 5 by great product well pleased with this product and also the service I received at your leigh branch, I ordered it online as I was stuck with an almost flat battery, picked it up one hour later and was soon on my way. thankyou, 14 March 2016
    Rated 5 out of 5 by all you need in 1 product Got at sale price so that made it a good buy very well made, is easy to use 12 March 2016
    Rated 4 out of 5 by Good value for money Got this product as it was in promotion, 40% off. Very pleased with it as it saved me from having to get a third party to rescue me. Managed to fully charge a completely drained battery in a little over 8 hours on the "fast charge" option. The only downside are the cables that are a bit short. The device seems to be very sturdy and should last a few good years. 09 March 2016
    Rated 3 out of 5 by Ring RCB320 batt charger/Halfords cr battery I am not urge what item is faulty, I think it may be he charger. I charged my battery fully(battery charge indicator showers Green). However the charger continued to show battery being charged and 2amps indicated on the ammeter an the indicator light indicating "Charging". This continued for 3 days with the charge control switch on 12v Fast. In the instruction book it states that when the battery is fully charged the "Fully Charged Light" will light. The battery (Halfords Silver 5000 HSB053 Yuasa) is a year old and has a 5 year guarantee. So you see my quandary, is it the charger or the battery faulty!!! Perhaps you can help? The local staff dismissed it said it carried on trickle charging. The instruction book states that this occurs when the charge switch is on12v slow. 09 March 2016
    Rated 5 out of 5 by Great machine Best priced quality charger I could find after a lot of research. €49.99 euro third price of anything near in standard. Charged 3 my car battery's efficiently. I have a number of classic cars and it's just the job. Strong heavy quality feel to iylt. 08 March 2016
